S_Blur Blurs the source clip by an arbitrary amount using a gaussian, triangle, or box filter. This effect should render quickly even with very large Width values. Use the Blur Rel X and Y parameters for a more horizontal or vertical blur direction. In the Sapphire Blur+Sharpen effects submenu. Inputs: Source:  The clip to be processed. Mask:  Optional.   If provided, the blur is only performed on regions of the source clip specified by the bright areas of this input. Pixels outside this mask are not blurred, and do not contribute to the resulting blurred pixels within it. This input can be affected using the Invert Mask, or Mask Use parameters.

Parameters:

Effect:   Popup menu,  Default: Blur Color.
Selects between full color or monochrome result.

Blur Color:  blurs all the channels of the source input.

Blur Mono:  makes the source monochrome and then blurs the resulting single channel (faster).

Blur Amount:   Default: 0.1,  Range: 0 or greater.
Scales the width of the blur. This parameter can be adjusted using the Blur Amount Widget.

Blur Rel:   X & Y,   Default: [1 1],  Range: 0 or greater.
The relative horizontal and vertical blur widths. Set Blur Rel X to 0 for a vertical-only blur, or set Blur Rel Y to 0 for a horizontal-only blur. This parameter can be adjusted using the Blur Amount Widget.

Brightness:   Default: 1,  Range: 0 or greater.
Scales the brightness of the result.

Scale Opacity:   Default: 1,  Range: 0 to 10.
Scales the opacity (alpha channel) of the result.

Offset Darks:   Default: 0,  Range: -8 to 2.
Adds this gray value to the darker regions of the result. This can be negative to increase contrast.

Mix With Source:   Default: 0,  Range: 0 to 1.
Interpolates between the blurred result (0) and the original source (1). 0.1 can give a nice misty effect since it mixes only a little of the source in.

Filter:   Popup menu,  Default: Gauss.
The type of convolution filter to blur with.

Box:  uses a rectangular shaped filter.

Triangle:  smoother, uses a pyramid shaped filter.

Gauss:  smoothest, uses a gaussian shaped filter.

Subpixel:   Check-box,  Default: off.
Enables blurring by subpixel amounts. Use this for smoother animation of the Blur Amount or Blur Rel parameters.

Soft Borders:   Check-box,  Default: off.
If enabled, transparent borders are added to the input image before processing. This allows the result to include soft edges beyond the original image size. When off, the effect only occurs within the frame and the result will retain an edge at the borders. This parameter does not appear in FCP or DF because those applications don't support image expansion.

Invert Mask:   Check-box,  Default: off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.

Mask Use:   Popup menu,  Default: Luma.
Determines how the Mask input channels are used to make a monochrome mask.

Luma:  the luminance of the RGB channels is used.

Alpha:  only the Alpha channel is used.

Show Blur Amount: Check-box, Default: on.
Turns on or off the screen user interface for adjusting the blur amount parameters.
